Find the y-intercept of the line 18x–y=5.
2 answers:
Answer:
y-intercept = -5
Step-by-step explanation:
Slope-intercept form of a linear equation:
(where is the slope and is the y-intercept)
In order to find the y-intercept of the given line, rearrange so that it is in slope-intercept form:
Given equation:
Add y to both sides:
Subtract 5 from both sides:
In slope-intercept form:
Therefore,
- slope (m) = 18
- y-intercept (b) = -5

<u>Answer:</u>
<h2>a.
x ≈ 3.72</h2><h2>
b. x ≈ 8.08</h2><h2>
c. x ≈ 3.94</h2>
<u>Steps:</u>
a.
x = 7×tan(28)
x = 7×0.531..
x ≈ 3.72
b.
x = 7/cos(30)
x = 7/0.86..
x ≈ 8.08
c.
x = 6×sin(41)
x = 6×0.65..
x ≈ 3.94
